Yes including yours :). I am building one myself for our internal infrastructure. There is definitely a need to build a service that wraps on top of AWS but you have to go niche. Cannot do everything.
I am literally trying to solve a problem in AWS Infra right now where I want to setup PHP/Laravel apps on demand and all the tools that exist are way too complicated. I want a simple UI that asks me for the domain, github repo and a couple of questions (db/cache etc) and then boom. It setups the site.
What if I tell you I have a service that is able to do that it takes away all the complexities. You literally need no understanding of the underlying services, you just benefit from its flexibility, and simplicity.
